Library of Congress call numbers which contain mixed alphameric notations are not readily adaptable for computer sorting. Some editing is required if the sorted call numbers are to correspond to the library shelf arrangement. A PL/1 subroutine that performs such editing is in use at Eastern Illinois University. The computer programs are appended.…

This progress report on a pilot project involving the reclassification of 1,000 titles in the Providence Public Library using data processing techniques covers the period October 1, 1967, to December 31, 1967. The major activities and accomplishments, problems, significant findings and events, dissemination activities, staff time, and future…

STARTING FROM A MODEL OF CONTEMPORARY MECHANIZED RETRIEVAL SYSTEMS AND THE CHARACTERISTICS OF INDEXING LANGUAGES USED THEREIN, THE AUTHORS DEVELOP A RATIONAL BASIS FOR USE OF THE UNIVERSAL DECIMAL CLASSIFICATION (UDC) IN THIS CONTEXT. PRACTICAL DESIGN CONSIDERATIONS FOR THE USE OF UDC IN A MECHANIZED RETRIEVAL SYSTEM ARE DISCUSSED. EXAMPLES ARE…

Objectives of this project were: (1) to uncover problems a public library might encounter in reclassifying its collection from the Dewey Decimal Classification to the Library of Congress Classification, (2) to apply data processing to the tasks, (3) to establish procedures for reclassification, and (4) to provide a cost estimate for the conversion…

This paper reviews the need for and possibilities of developing an adequate and universal classification and coding system for educational media. (Editor)

THE FOLLOWING IS THE FULL TEXT OF THIS DOCUMENT: As the number of software programs grows--and current estimates put the number at around 30,000--identifying a particular program can be a problem. R.R. Bowker Company, the administrator of the U.S. ISBN agency, has announced one solution to the identity problem--it will assign International…

A clustering algorithm which is tree-like in structure, and is based on user queries, is presented. It is compared to some existing algorithms and is found to be superior. (Author)

A suite of computer programs has been developed for representing the full text of lengthy documents in vector form and classifying them by a clustering method. (Author)

Describes method of automatic document classification in which documents classed as QA by Library of Congress classification system were clustered at six thresholds by keyword using single link technique. Automatically generated clusters were compared to Library of Congress subclasses, and partial classified hierarchy was formed. Twelve references…

Modal Profile Analysis (MPA) is a Fortran IV program for the identification and cross validation of relatively homogenous subgroups within a dimensional or ordination space. This classification approach is designed for use with several samples in a multiple replication design. The program consists of three stages: (1) identification of preliminary…

This paper briefly summarizes the characteristics of 14 of the currently most popular computer pragrams for cluster analysis. Also provided is a subjective ranking of the programs in terms of their versatility and usability. (Author)

In order to contribute to the success of several studies for automatic classification, indexing and extracting currently in progress, as well as to further the theoretical and practical understanding of textual item distributions, the development of a frequency program capable of supplying these types of information was undertaken. The program…

Using parameter estimates the computer program calculates the negative hypergeometric distribution and computes the classification proportions: suitable-accepted, suitable-not accepted, not suitable-accepted, and not suitable-not accepted. (RC)

As a result of a concern over the adequacy of teacher rating instruments, a project was begun to develop a pool of items describing teacher behavior. Most of the items were derived from the literature; some were written by the project. The item pool presently consists of 1137 items subsumed under 19 categories. Examples of categories are: personal…
